 Example: `set var = "World"`
 
+## input var *bytes = type *ibytes
+
+Creates a new variable that is `bytes` long, that reads the first `ibytes` of input.
+
+Example: `input str *5 = string *3` (3 bytes of input, remaining 2 bytes are left blank)
+
 ## if bool
 
 Runs code if a boolean is true.
 
 Example: 
 ```
-create bool *1 = false
-create var *5 = "Hello"
+# If a boolean is true
 if bool {
-  set var = "BASM!"
+  set str = "Hello"
+}
+
+# If second byte of var and third byte of var are equal
+if var[1] == var[2] {
+  set bool = true
